    Answer:

    P = 96 J

    Explanation:

    Given that,

    Weight of the book, W = mg = 8 N

    It is placed at a height of 12 m

    We need to find the potential energy of the book. The potential energy of an object is given by the formula as follows :

    E = mgh

    mg = Weight

    E=8\ N\times 12\ m\\E=96\ J

    So, the potential energy of the book is 96 J.
